Force Correlations in Disordered Magnets
Cathelijne ter Burg, Felipe Bohn, Gianfranco Durin +2
We present a proof of principle for the validity of the functional renormalization group, by measuring the force correlations in Barkhausen-noise experiments. Our samples are soft…
A multi-band analogue frequency sensor with sub-MHz resolution based on a Vortex Nano-Oscillator
Alex S. Jenkins, Lara. San Emeterio Alvarez, Roberta Dutra +3
As the Internet of Things (IoT) becomes more integral to how we live our lives and society becomes ever increasingly connected, the need for efficient nanoscale radio frequency det…
Playing with universality classes of Barkhausen avalanches
Felipe Bohn, Gianfranco Durin, Marcio Assolin Correa +4
Many systems crackle, from earthquakes and financial market to Barkhausen effect in ferromagnetic materials. Despite the diversity in essence, the noise emitted in these dynamical…
Universality and the collapse of multifractality in Barkhausen avalanches
Gustavo Zampier dos Santos Lima, Gilberto Corso, Marcio Assolin Corrêa +3
Barkhausen effect in ferromagnetic materials provides an excellent area for investigating scaling phenomena found in disordered systems exhibiting crackling noise. The critical dyn…
Quantitative scaling of magnetic avalanches
G. Durin, F. Bohn, M. A. Correa +3
We provide the first quantitative comparison between Barkhausen-noise experiments and recent predictions from the theory of avalanches for pinned interfaces, both in and beyond mea…
Magnetoimpedance effect at the high frequency range for the thin film geometry: Numerical calculation and experiment
M. A. Corrêa, F. Bohn, R. B. da Silva +1
The magnetoimpedance effect is a versatile tool to investigate ferromagnetic materials, revealing aspects on the fundamental physics associated to magnetization dynamics, broadband…
Statistical properties of Barkhausen noise in amorphous ferromagnetic films
F. Bohn, M. A. Corrêa, M. Carara +3
We investigate the statistical properties of the Barkhausen noise in amorphous ferromagnetic films with thicknesses in the range between and nm. From Barkhausen noise…
Universal properties of magnetization dynamics in polycrystalline ferromagnetic films
Felipe Bohn, Marcio Assolin Correa, Alexandre Da Cas Viegas +3
We investigate the scaling behavior in the statistical properties of Barkhausen noise in ferromagnetic films. We apply the statistical treatment usually employed for bulk materials…
Interlayer coupling in spin valves studied by broadband ferromagnetic resonance
D. E. Gonzalez-Chavez, R. Dutra, W. O. Rosa +3
Magnetization dynamic response of coupled and uncoupled spin valves with structure NiFe(20 nm)/Cu(t_Cu)/NiFe(20 nm)/IrMn(10nm) were probed using broadband ferromagnetic resonance a…
Beyond power laws: Universality in the average avalanche shape
Stefanos Papanikolaou, Felipe Bohn, Rubem L. Sommer +3
We report the measurement of multivariable scaling functions for the temporal average shape of Barkhausen noise avalanches, and show that they are consistent with the predictions o…
Dynamic hysteresis in Finemet thin films
L. Santi, R. L. Sommer, A. Magni +3
We performed a series of dynamic hysteresis measurements on three series of Finemet films with composition FeCuNbSiB, using both the longitudinal magnet…
Investigation of scaling properties of hysteresis in Finemet thin films
L Santi, L. S. Dorneles, R. L. Sommer +4
We study the behavior of hysteresis loops in Finemet FeCuNbSiB thin films by using a fluxometric setup based on a couple of well compensated pickup co…
Domain size effects in Barkhausen noise
M. Bahiana, Belita Koiller, S. L. A. de Queiroz +2
The possible existence of self-organized criticality in Barkhausen noise is investigated theoretically through a single interface model, and experimentally from measurements in amo…
